1. No, you cannot intermix families (cygnets), because the older swans may intentionally fight with the cygnets which could cause serious injury and even death to the cygnets.

2. Each state has different laws so you will need to check into your state laws. We would suggest you contact Jack Long Exotic Waterfowl in California for guidance.

However, in general, if you breed and sell swans or other waterfowl, you will need a breeder's license. So, not sure you want to go down that road. You might check with Jack Long also regarding good home placement.

3. We would suggest you not introduce another swan unless you are prepared to build an introductory pen to house the new swan for 2 weeks so it can acclimate itself to you, the other swans and the new habitat. The pen must be enclosed top to bottom to prevent predators from digging under or crawling over into the pen and attacking the swan. The pen must be 1/2 in the water and 1/2 on land with zero entrance (no steep or abrasive banks/surfaces). A feeder should be placed in the pen. Any sign of aggression from any of the swans means that this is not going to work and you will need to find a safe suitable home for the new swan.

Additionally, male swans do not typically re-pair if something occurs to their mates. This is an individual attribute, but there are no guarantees that your swan will accept another mate. He will do just fine alone. You cannot get another male swan or there will be a fight, so you need to have a gender test conducted on both swans (new and old) to ensure you are getting an opposite gendered swan.

So, the questions regarding a new swan are: Are you prepared to build and use an introductory pen, for fights that might ensue and upset the present pecking order, for more cygnets, and other labor issues related to the care of many more swans?

Typically, Australian Black Swans mate and produce 1-8 cygnets twice a year. This means just with your current group of 3 pair, you are looking at 3-24 cygnets annually. Add another pair and you have 4-32 cygnets each year. How are you going to deal with the high numbers if you cannot sell or find a good home? These are all issues you will need to decide and we strongly suggest you speak with Jack Long or other knowledgeable/reputable swan specialist in your area that can determine your situation under your state exotic animal laws..
